LT3797EUKG#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3797 is 100V, but it's recommended to keep it below 90V for reliable operation.
  • To ensure the LT3797 operates within its SOA, monitor the input voltage, output current, and junction temperature. Keep the input voltage below 90V, output current below 3A, and junction temperature below 125°C.
  • The EN (enable) pin is used to turn the converter on and off. Connect EN to VIN to enable the converter, or connect it to GND to disable it. You can also use a logic signal to control the EN pin.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value. The datasheet provides guidelines for inductor selection, and you can also use the LT3797 demo board as a reference.
  • Keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise. Place the inductor and diode near the IC, and use a shielded inductor to reduce EMI. Follow the layout guidelines in the datasheet and demo board for optimal performance.
